A M13 virus based SERS nanoprobe is presented. Gold nanocubes closely aligned into chains along the length of the virus intensify Raman signals of various reporter molecules serving as specific labels. An antibody is expressed at one end to detect the analyte. This new SERS nanoprobe holds promise for infinitesimal and multiplexed detection of any antigen.
